Help! Grand not firing

[kingdal]

Hey reoville, i badly need your help. Just today my grand stopped firing and i cant figure out why. When i hit the button, i see arcing but the coils dont light up, or if it does it takes a real long time. And when i take the battery out, the button top is noticeably hot. I think theres a short somewhere but the atty (a derringer with dual 26 coils at 0.33) works fine on my peko. The battery is one i bought brand new last week from illumn, an LG HE2 button top so hopefully not a counterfeit. The grand, i just received back from rob. Its got the new 510 and gold contacts.

I thought initially that the pos cintact may have been pushed out of alignment but its pretty centered and fixed tight. I've owned a reo for the last three years so i'm not new at this but in this case, i dont even know where to look.

Anyone have any suggestions? Thanks

I don't know if the arc'ing will cause that, but the only thing I know is to put some deoxit gold on the contact, spring and both batt ends. If the atty meters fine with top cap and DT if the DT has any metal on it. Then I would just give it a good bath and reapply deoxit in case you got a tiny piece of kanthal in the 510 anywhere or something else causing it to short when you attach the atty. Other than that, someone else will have to come along that knows much more than I do. Those are pretty simple things that you probably already know, but at least this subs me to the thread so I can learn other things to try lol Hope you get it fixed soon

I assume you are not getting the arcing when no atty is on the mod? If you are then that would point to a short in the 510 connector. Otherwise I would try adjusting the centre pin on the grands 510. Just remember that is is a reverse thread!

This would be my guess too, or something in the well/510 shorting? Like a random piece of wire clipping?

If all else fails, try swapping the atomizer. That will at least tell you if it's the atty or the REO. In general, it's easiest to try to narrow down the problem from "big to small", i.e., swap out major components first, then start digging around once you've found the culprit.

I would clean your positive contact and try another atty to start . Keep us in the loop

I'd make sure the atty screws are tight, that happened to me.

Thanks so much for all the replies. So to answer the suggestions, this is what i tried:

No atty, no arcing. Good yes?
Washed out the Grand. I didnt find any loose material in the 510
Tried it with the derringer. Problem is same
Put another atty on it. Problem is same. Both attys work fine on a diff mod
Changed to another battery. Problem is same. For what its worth, if i hold the button down long enough, the button top on the batt gets really hot

Im traveling unfortunately so no access to deoxit. Same with adjusting the 510 pos screw. I'll try that when i get home. But for the meantime, any other suggestions?

I was thinking to take it apart and look under the delrin but ive never done it with the new 510. Anyone know a video on this? Thanks again

On occasion I have the same issue and find that I've loosened my atty of the adjustable 510 has moved a little, it doesn't take that much to break that connection. I bet the 510 pin move just a bit if there's nothing else obviously wrong.

Be careful removing that delrin cover. When you go to put it back on its really easy to strip the screw hole. Its soft aluminum. Just snug the screw and don't turn it more then that! I've done it and many others have and you'll have to send it back in for the fix.

I'd suggest removing the spring screw at the bottom and clean the screw threads and the hole on the reo.. That's your ground connection. If its all dirty then you have a weak connection.

Other then that id also raise the adjustable 510 screw to make sure its making a solid connection to the atty. Make sure the small 510 screw is still in there.. They fall out sometimes in shipment. Hex head and you should of got a allen key for it.. Its reverse threaded so turning it to the right raises the screw and to the left lowers it.

This happens on mine!

As you are getting no arcing without an atty that pretty much eliminates a short in the 510 connector itself.

A poor connection at the hot spring, a poor connection between the positive pin and the switching bar or loose adjustment screw would all cause the problem.

I would try the adjustment screw first as it's probably the most likely, as they can move when you remove the atty. Just turn it clockwise and this will move positive connection further up towards the one in the atty. Pretty sure its a 1.5mm hex key.

Good luck!

Thanks for the suggestions. I let out the 510 screw but nothing. Generating heat on the coils but really, really slowly. Right now, Im thinking the positive leaf got pushed out of position, more towards the back of the mod so it doesnt make good contact with the batt. How do i readjust that positive leaf?

Edit: found the video on the web site Just need to wait till i get home to try it

Make sure your spring is tight If you cant find the problem please send the mod in I will find it and fix it .

 

[Infernal2]

Yep, check your spring. Also check your positive contact inside the delrin housing and make sure its centered. Also, if you use a button topper on your firing pin, take it off and clean the delrin barrel, I've had things get stuck to it before and play hell with the throw distance.

I had this very same problem. New grand with brand new HE2s purchased from illum. I tried mutiple atomizers and destroyed 5 contacts with and without dexoit. I think I narrowed down the problem to one of two things 1) there is some sorta residue on the battery from manufacture or the little disc that protects the positive end or 2) the size shape of the button on the HE2.. all the pitting from the arcing is around the outside edge of the button which leads me to believe that the button is a little to tall so that the contact hits the back side of the button and only makes partial contact. I finally gave up on the He2s put a fresh contact and started using flat top batteries.... havent had a problem since

oh wow, thanks for sharing that, that's interesting

I think that was it! For whatever reason, the pin wouldnt go down enough to make good contact with the batt. When i took the cover off, the pin came down an extra millimeter. So far, the grand seems to back to normal. Will use it over the next few days to make sure.

Thanks Infernal and everyone else for chiming in!

awesome!!!

 

[kingdal]

Eh spoke too soon. Put a battery in the grand this morning and immediately got a weak hit and worse, smelled something burning (not the wick). I think i have a short somewhere. Nothing to it now but to take it apart and see what's happening. Wish me luck!

Sorry to hear that it's not fixed, but that something burning might lead you to the source of your frustrations.
